JOHN DOWNS, OF J OHNSTOWN, PENNSYLVANIA.

DEVICE FOR POURING METAL.

SPECIFICATION forming part of Letters Patent No. 510,062, dated December5, 1893.

Application led May 27, 1893. Serial No. LL75,691. (No model.)

To @ZZ whom it may concern:

Be it known that l, JOHN DOWNS, a citizen of the United States, residingat Johnstown, in the county of Cambria and State of Pennsylvania, haveinvented certain new and useful Improvements in Devices for PouringMetals; and I do declare the following to be a full, clear, and exactdescription of the invention,such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the letters of reference markedthereon, which form a part of this specification.

'Ihe object of my invention is a device for pouring iron, steel or othermetals in a luid state.

In the accompanying drawings Figure l is a sectional view of my metalpouring device. Fig. 2 is a top view ot' the same. Fig. 3 is a frontview. Fig. 4 is a perspective view of a plug used in my metal pouringdevice, and Fig. 5 is a perspective View of al stopper used on thevalve.

In the drawings A represents a melting vessel, to the bottom. of whichmy pouring device vis attixed by proper bolts.

A is the metal casing of the vessel A.

A2 is an inside lining of suitable refractory material arranged so as toform an opening in the center through which the metal will flow, plainlyseen in Fig. l. At the bottom of this opening I put a hollow plug madeto tit tightly when in position as seen in said last named iigure.. Thisorifice is made tapering from the top to the bottom, so that the plug A3will fit tightly therein, it being also made tapering. This plug A8 willalso be made of good refractory material, capable of` resisting as higha degree of heat as the metals are subjected to. This plug A3 has anopening down through the center for the Iiow of the metal fluid. Inorder to make the space above this plugperfectly tight I put a suitableplastic substance around the plug A3 sce d in Fig. l Where this plasticsubstance is represented. This forms a tight joint around the plug andholds the metals in the Space above the plug A3 and valve C.

B B is the metal casing or frame work around the lining A2. This framework or casing has lugs b b with bolt holes for the purpose of securingthe frame to the vessel A. b2 b2 are bolts to secure this frame B to thevessel A.

C isa plug or valve to control the flow of the metal.V This valve orplug is made of good refractory material capable of resisting thehighest possible degree of heat usually attained in melting such metalsas iron, steel, &c. It is made ilat and is so constructed as to slideover the top of the plug A3 and form a tight joint over the orifice ainsaid plug.

The bolts ee, pass through the projection b of the Yframe work B. Thisprojection also forms a vrest for the valve C.

e3, e3, represent the heads of the securing bolts; e2, e2, the nutsthereon, and e e the springs around said bolts to force the portion Ddown upon the valve and hold it from accidental movement.

In operation when the uid is ready to be poured, the valve or plug C isdrawn out by any suitable means. The block D will hold the fluid back incase the valve becomes diminished in size. An opening is made in theside of the frame B for this valve C.

It will be easy to repair this pouring device. To do this the frame B,will be unbolted from the vessel A, and when thus detached, the plug A3may be knocked out and another put in its place, or the other parts maybe repaired or replaced as occasion requires.

Having thus described my invention, what I claim, and desire to secureby Letters Patent of the United States, is-

The combination of the filling vessel, the shell havinga dischargeopening and communicating with the vessel, the lining in the shell, theconical plug having an opening and arranged in the lining, the openingor passage in one side of the shell and lining above the conical plug,the valve arranged in said passage above said plug and controlling theopening of the plug, the block having a recess to receive the valve andhaving a kerf or groove in each end, and spring bolts passing throughthe said grooves or kerfs and the shell, and serving to press the blockagainst the valve and prevent it from improper movement.`

In testimony whereof I aftix my signature in presence of two witnesses.

'JOHN Downs.
